It's bad enough that male students constitute only 45 percent of four-year-college undergraduates these days.

But now their universities are trying to purge this shrinking group of XY-chromosome-bearers of their "toxic masculinity." The main theme: Men bad, women good. Talk about punching down!

The report from The College Fix is grim:

At a mandatory freshmen orientation training at Gettysburg College in August, male students had to watch a documentary which stated in part that the “three most destructive words” a boy can hear growing up is “be a man.” The freshmen also went through breakout sessions in which they were told mass shooting sprees are rooted in toxic masculinity.

And how about this:

The “Thrive” club, part of the Claremont colleges consortium which meets as a “safe space” to talk about mental health, advertises that “masculinity can be extremely toxic to our mental health, both to the people who are pressured to preform it and the people who are inevitably influenced by it.”

And:

Last year, Vanderbilt University hosted “Healthy Masculinities Week,” led in part by Jackson Katz, the first man to minor in women studies at the University of Massachusetts Amherst.

Katz criticized actors such as Arnold Schwarzenegger and Sylvester Stallone for their muscular physiques, which have gotten “larger” over the years. According to the presentation, “hyper-masculinized sporting culture” has also advanced unhealthy masculinity.

And:

“How has the concept of masculinity contributed to the perpetration of violence in our society?” asks the [University of North Carolina] Men’s Project website.

Duke University started a similar program this semester for male students to reflect on topics such as patriarchy, male privilege, rape culture, pornography, machismo and “the language of dominance,” Fox News reported.

A favorite theme of the toxic-masculinity curriculum is domestic terrorism, which of course has nothing to do with, say, ISIS:

Many at the University of California-Merced are mourning the 18-year-old student who went on a vicious stabbing spree before being shot and killed by a campus police officer, with a “R.I.P” tribute to Faisal Mohammad on Facebook gaining massive support among the campus community.

Faculty also held a “teach in” Monday night that was conspicuously devoid of discussions of radical Islam, and instead delved into topics such as how society’s notions of masculinity pressure men.

After his rampage, Mohammad was found to have an image of the ISIS flag, a handwritten manifesto with instructions on how to behead someone, and reminders to pray to Allah, but the campus community appears to largely agree with authorities and university officials who insist his motives were grounded in revenge for being kicked out of a study group.

And even more recently, as the Fix article reports:

For example, a class at Dartmouth College this semester, “The Orlando Syllabus,” identifies so-called toxic masculinity as playing a role in the mass murder spree at a Florida club during the summer. This despite the fact that the gunman, Omar Mateen, told police on the phone as he committed the massacre he did it on behalf of ISIS.

So my question is: Colleges, why not take the next step and ban men from campus altogether if they're so toxic to be around?
